Those having skill in the art will recognize that thestate of the art has progressed to the point where there is littledistinction left between hardware and software implementations ofaspects of systems; the use of hardware or software is generally (butnot always, in that in certain contexts the choice between hardware andsoftware can become significant) a design choice representing cost vs.efficiency tradeoffs. Those having skill in the art will appreciate thatthere are various vehicles by which processes and/or systems and/orother technologies described herein can be effected (e.g., hardware,software, and/or firmware), and that the preferred vehicle will varywith the context in which the processes and/or systems and/or othertechnologies are deployed.

Further,those skilled in the art will recognize that the mechanical structuresdisclosed are exemplary structures and many other forms and materialsmay be employed in constructing such structures.

The need for mechanisms, devices, methods, systems, and structures whichmay be used to alter hurricanes either in their strength, their origin,or their direction of travel has been realized. Billions of dollars ofdestruction and damage is regularly attributable to hurricanes andhurricane-like tropical storms. Thus, great interest has arisen incontrolling these powerful storms. Conventionally, it has been proposedto deploy barges equipped with upward-pointing jet engines into thepaths of hurricanes. The jet engines would theoretically be configuredto create mini-cyclones which would consume oceanic energy and thusprevent or suppress such high powered weather systems.

Another potential solution involves the use of Dyn-O-Gel, a polymer thatmay absorb as much as 1,500 times its own weight in water to deprive ahurricane of atmospheric moisture. The concept involves the use ofairplanes to drop Dyno-O-Gel into hurricanes to deprive them of moistureand thus of latent heat. The powder is suggested to convert into a gelwhen the atmospheric moisture is captured and would then reliquify whenit encounters higher-osmolality ocean water.

The jet engine solution has been met with great skepticism and the costand feasibility are very uncertain. The use of a moisture absorbing gelrequires the deployment of a huge volume of the absorbing gel material.Also, the use of a moisture absorbing material is still in the testingphase. The gel material after absorbing moisture falls to the ocean andmay dissolve. Depending on the chemical composition of the gel, the gelbe regarded as a pollutant. These various shortcomings considered, itmay be desirable to provide a different approach for altering hurricaneand/or tropical storm activity by providing a structure and method thatsolves at least one or more deficiencies of other systems known in theart. Because hurricanes and other tropical storms derive their energyfrom warm ocean water, it is logical to harness the great energies ofthe Earth's fluid envelopes to suppress or alter hurricanes or othertropical storms, and/or to employ the powers of motion within theseenvelopes over long time-intervals to modulate at least one property ofan envelope that is exploited over much shorter time-scales and/or muchmore limited spatial scales for energizing a hurricane.

A potential solution for cooling warm surface water has been explored byresearchers with Atmocean, Inc. of Santa Fe, N. Mex. In the Atmoceanapproach, an elongated tube with a buoy is used to create an upwellingeffect. The upwelling effect drives cold water from a depth to thesurface.

It is well known that a hurricane's primary energy source is the releaseof the heat of condensation of water vapor condensing at high altitudes,with solar-derived heat being the initial source for evaporation.Therefore, a hurricane may be seen as a giant vertical heat engine,albeit one dependent upon mass supplied by largely horizontal flows.Water condensation leads to higher wind speeds, as a fraction of thereleased energy is converted immediately into thermal energy and thenceinto mechanical energy, the faster winds and lower pressures associatedwith them in turn cause increased surface evaporation and thus even moresubsequent condensation. Much of the released energy drives updraftsthat increase the height of speeding up condensation. This gives rise tofactors that provide the system with enough energy to beself-sustaining, and result in a positive feedback loop that continuesas long as the tropical cyclone can draw energy from a thermal reservoirand isn't excessively sheared along its vertical extent. In this case,the heat source is the warm water at the surface of the ocean. Withoutthis thermal reservoir to support it a hurricane or other similar stormwill not commence, will be weaker, or will die out as the positivefeedback loop diminishes to sub-threshold levels or never gets abovethem.

Referring now to FIG. 1, a cross-section of a water-borne structure orvessel 100 is depicted. Vessel 100 is a tub-like structure having one ormore walls 110 and a bottom 115. Vessel 100 may be held buoyant in thewater by one or more buoyancy tanks 120 which may be used to maintainthe buoyancy of vessel 100 and further may be used to control the heightof walls 110 above the water level. Vessel 100 also includes a conduit125 whose horizontal cross section is substantially smaller than thehorizontal cross section of the tub portion 130 of the vessel defined bywalls 110. In an exemplary embodiment, conduit 125 extends well belowthe ocean surface including depths below the ocean's thermocline.

In most circumstances, most of the sunlight impinging on the oceansurface is absorbed in the surface layer. The surface layer thereforeheats up. Wind and waves move water in this surface layer whichdistributes heat within it. The temperature may therefore be reasonablyuniform to depths extending a few hundred feet down from the oceansurface. Below this mixed layer, however, the temperature decreasesrapidly with depth, for example, as much as 20 degrees Celsius with anadditional 150 m (500 ft) of depth. This area of rapid transition iscalled the thermocline. Below it, the temperature continues to decreasewith depth, but far more gradually. In the Earth's oceans, approximately90% of the mass of water is below the thermocline. This deep oceanconsists of layers of substantially equal density, being poorly mixed,and may be as cold as −2 to 3° C.

Therefore, the lower depths of the ocean may be used as a hugeheat/energy sink which may be exploited by vessel 100. When vessel 100is deployed at sea, waves 135 may lap over the top of walls 110 to inputwarm (relative to deeper waters) surface ocean water into tub 130. Tub130 will fill to a level 140 which is above the average ocean leveldepicted as level 145. Because of the difference between levels 140 and145, a pressure head is created thereby pushing warm surface ocean waterin a downward direction 150 down through conduit 125 to exit into thecold ocean depths (relative to near surface waters) through one or moreopenings 155. In an exemplary embodiment, the depth of opening 155 maybe located below the ocean's thermocline, the approximate bottom ofwhich is depicted as line 160. This cycle will be continuous in bringingwarm surface ocean water to great depth as ocean waves continue to inputwater into tub 130.

If many of vessel 100 are distributed throughout a region of water, thetemperature of the surface of the water may be altered. Referring toFIG. 2, an array 200 of vessels 100 is depicted. Such vessels may bearranged in a plurality of ways, including but not limited topositioning them in a water region in an array, such as array 200, in arandom placement 300, as depicted in FIG. 3, within a region, and/or inany other arrangement. It may be desirable to determine the mostsuitable and/or optimal arrangements through computer modeling or othertechniques. Referring now to FIG. 5, it may be seen that many vessels100 may be dispersed throughout hurricane prone regions such as but notlimited to the Gulf of Mexico 500 or the Caribbean Sea. Vessels 100,depicted for illustrative purposes only and not to scale are shown beingdispersed in a relatively random pattern. Boats 510 may be used to towvessels to desired locations. Also, other means such as self propulsion,airlifting, towing, or other methods to move vessels may also be used.In another embodiment, vessels 100 may be anchored in a variety of ways,including but not limited to anchored to the bottom, anchored usingsubsurface weights, anchored using sea anchors, or anchored to eachother.

Referring again to FIG. 1 vessel 100 may be one vessel in a system foraltering water surface temperature. As such the tub 130 is one type of aholding vessel configured to hold water. Tub 130 includes at least onewall 110 (but may include multiple walls) which are coupled to a bottomportion 115. The at least one wall 110 extends above the water level andthe bottom portion 115 is configured to be submerged. At least oneconduit 125 extends from the bottom of the tub 130. In some, but notnecessarily all, applications, it may be desirable for conduit 125 tohave a length that extends to a depth at which the temperature of waterat the depth (e.g., below line 160) is substantially less than water atthe surface

Vessel 100 may be held buoyant by both the materials used to constructvessel 100 as well as at least one ballast tank 120. Tanks 120 may becoupled to at least one pump 170 and at least one valve 180. Inaccordance with an exemplary embodiment, the height of wall 110 abovethe average water surface level may be varied and controlled dependingon the time-varying height of the local waves and depending on thedesired flow rate through conduit 125. One way in which to vary theheight of wall 110 above the average water level 145 is to pumpatmospheric air into tank 120 or out of tank 120. In conjunction withpump 170, valve 180 may be used to draw water into or out of tanks 120.In accordance with another exemplary embodiment, it may be desirable tohave the ability to mechanically raise or lower at least a portion ofwall 110 relative to the rest of the structure. It may also be desirableto control the raising and lowering of all or part of wall 110 inresponse to conditions adjacent to vessel 100 (e.g., water temperature,wave height).

In another embodiment, water flow into vessel 100 may be via openings175 in wall 110, rather than over the top of wall 110. Such openings maybe configured to preferentially allow flow into vessel 100, instead ofout of the vessel. In some embodiments, openings 175 are passive, usingflaps, checkvalves, rotating drums, or similar mechanisms to supportunidirectional flow. In other embodiments, openings 175 are activelycontrolled, utilizing motorized or variable setpoint flow controldevices such as valves, flaps, rotating drums, or similar mechanisms.

Walls 110 and bottom portion 115 as well as other parts of vessel 100may be constructed of any of a variety of materials and preferably of amaterial substantially resistant to degradation in water. For example,vessel 110 may be substantially constructed from concrete, polymers, atleast one of metals or metal alloys, fabrics, reinforced fabrics, and/orcomposite materials. In some applications, it may be advantageous forthe construction materials to resist degradation only for a limitedperiod of time, as degradation of the structure may diminish oreliminate expenditures associated with post-application retrieval of thestructure. Furthermore, it may be advantageous to allow the structure tosink below the water surface or to the water bottom after application,where degradation may be preferred to occur. In an exemplary embodiment,conduit 125 may be formed of any of a variety of materials includingboth rigid materials and flexible materials. It may also be desirable touse stiffening structures in the conduit depending on the type ofmaterials used. Such stiffening structures aid in maintaining the shapeof conduit 125 under pressure and under stress. The stiffeningstructures may be placed at one or more locations along the length ofthe conduit. Further, such stiffening structures may be deployable andmay aid in deployment along with a conduit which may also be deployablefrom tub 130. In yet another exemplary embodiment, it may be desirableto form vessel 100 from a material which would be known to degrade overtime. This may be useful if it is known that a vessel has a desiredlifespan or term of usefulness. Once the vessel's use is done, thevessel could sink or be sunk where it could subsequently degrade at asubsurface location.

In an exemplary embodiment the holding vessel or tub 110 has ahorizontal cross sectional dimension that is substantially greater thana horizontal cross sectional dimension of the conduit 125. In anotherexemplary embodiment holding vessel or tub 100 has a horizontal crosssectional dimension and/or shape that is substantially the same as thecross sectional dimension and/or shape as conduit 125. The pressure headcreated by the weight of the column of water above the conduit which isabove the line 145 is used to pressurize the descending water in conduit125. In an exemplary embodiment it may be convenient to have a powersource 190 on board vessel 100. Power source 190 may be any of a varietyof power sources, including but not limited to a solar cell, a windgenerator, a wave power generator, a turbine turned by water descendingin the conduit, a battery power source, a fuel powered power source, athermoelectric power source, etc.

In accordance with an embodiment a vessel 600 is depicted in FIG. 6having a conduit 625. Disposed within conduit 625 is a turbine 630.Turbine 630 may be driven by the flow of water through conduit 625.Turbine 630 may be utilized for a variety of purposes including but notlimited to generating power for a variety of purposes, maintainingbuoyancy, controlling buoyancy, driving other turbines, increasing thewater flow through conduit 625, etc.

In accordance with other exemplary embodiments it may be desirable toequip vessel 100 with one or more propulsion systems. Referring now toFIG. 4, a propulsion system may be in the form of a sail or a propeller450 or other motorized propulsion producing device. Such a propulsivedevice may be powered by power source 460 or any other source of power.The propulsion system may be used to control the positioning of vessel100 such that it remains at a specific area, moves in a specificpattern, and/or moves to a completely new location. A rudder 470, fin,sail, or other steering device may be coupled to vessel 100 to helpguide vessel 100. Alternatively, a sail or a propeller 450 may beconfigured to change orientation to provide steering for vessel 100.Because different depths in bodies of water often have currents flowingin different directions or with different speeds, a propulsion systemmay involve the use of one or more sea anchors with mechanisms andcontrol systems to effect proper placement of the sea anchors. In oneexemplary embodiment, it may be desirable to construct vessel 100 with ashape such that its coefficient of drag is less in one direction thananother. This may be accomplished by making the dimensions of vessel 100longer in one direction than another, for example. Other methods andshapes may also be used to produce such an effect.

In accordance with another exemplary embodiment, vessel 100 may includea movable conduit in which at least a portion 480 of conduit 425 may bemovable in various directions in order to provide a propulsive force ina desired direction. In another exemplary embodiment, the movableportion may be one or more openings 455 which may be controlled, alongthe length of conduit 425. The propulsive force generated by water flowthrough conduit 425 may also be varied by opening and closing opening485 using a controlled access device such as door 490 (or other aperturecontrol devices such as but not limited to valves, etc.) that maycontrol the flow rate through conduit 425.

In an exemplary embodiment walls 410 of vessel 100 may be formed ofmultiple wall segments or multiple wall portions. The multiple wallsegments of walls 410 form a closed shape to contain water within vessel100. The wall segments may be curved or straight, may be movable in sucha way as to help let in water or alternatively to release water. In oneexemplary embodiment, vessel 100 may be permanently anchored to thewater floor, temporarily anchored to the water floor, tied to asubsurface weight, tied to one or more sea-anchors, or may be freelymovable. In one exemplary embodiment, vessel 100 is movable by couplingthe vessel to a propulsive vessel, such as a tugboat or the like. Inanother exemplary embodiment, vessel 100 may include a wind capturestructure, such as a sail 495 that may be used to harness wind power formoving the holding vessel. The wind capture structure may be used forcontrolling the amount that the at least one wall of the holding vesselextends above the water, that is it may also be used to provide lift tothe holding vessel 100 structure, to help control how far above thewater level that walls 410 extend. Sea anchors are functionally similarto sails, except instead of extending up into the atmosphere they aredeployed into the water. Thus, sea anchors or current capture structuresmay be used for similar purposes as sails and wind capture structures.These include moving or holding the vehicle, generating power, providinglift, etc. Also in an exemplary embodiment, vessel 100 may have a ramparea 475 or other wave altering area that helps to control how the wavesmove water over the sides of vessel 100. This wave-altering structuremay be a static or passive structure, or it may be an active device orstructure having one or more components that are actuated or powered inorder to have a time-dependent character or activity; the power for suchpurposes may be derived from any of the power-providing means discussedabove, or may be derived from the wave-action itself. Further, in anexemplary embodiment, vessel 100 may have any of a variety of shapesincluding but not limited to circular, elongated, non-circular, shapedin a manner which aids in passively controlling orientation relative towave motion, etc.

Referring now to FIG. 6, a vessel 600 is depicted. Vessel 600 includes aconduit 625 in which a turbine 630 is driven by the downward flow ofwater through conduit 625. In an exemplary embodiment, the turningturbine may be used for a variety of purposes including providing power,providing control, providing propulsive power, etc. In one exemplaryembodiment a secondary conduit 640 (which represents one or moreconduits) may be used to bring cold ocean water (such as belowthermocline 650) to upper areas of warmer surface water to aid incooling the warm surface water regions, enhance mixing of subsurfacewater with surface water, enhance mixing of surface water withsubsurface water, raising subsurface nutrients to the surface, bringingsurface nutrients to subsurface regions, etc. In one exemplaryembodiment, turbine 630 may be used to drive a second turbine 635 inconduit 640 that pumps water up through conduit 640. Further, othermechanisms may be used to bring subsurface water upwards. In mostplaces, deeper waters contain a greater concentration of nutrients thansurface water, so conduit 640 may also be used to transport dissolvednutrients from deeper waters to waters near the surface of the body ofwater.

Referring now to FIGS. 7 and 8 are exemplary diagrams of one or moregeneralized vessels 720 for holding and moving water, being towed by awatercraft 710. Movement of vessels 720 may be accomplished by any of avariety of methods and techniques including but not limited to thosedepicted. In the example of FIG. 7, a single vessel 720 is being towedto a desired position by a watercraft 710. As depicted in FIG. 8,multiple vessels 720 may be linked together and towed by a watercraft710. Further, many other configurations may be used includingself-propelled vessels, linking powered vessels with unpowered vessels,etc. Further, Vessels may be pulled, pushed or propelled.

Referring now to FIG. 9, a method 900 of maintaining an ocean wateralteration system includes providing at least one ocean water alterationvessel (process 910). Such systems are used for a variety of reasons andmay be used at various locations therefore, such vessels may need to bemoved to address positioning issues and goals. Movement or maintenancemay be addressed by attending the at least one ocean water alterationvessels by at least one watercraft (process 920). The maintenance mayinclude but is not limited to providing fuel for operations, or torepair or maintain the vessel itself.

The capability of the systems and methods described to enhance mixingbetween surface and subsurface water can be useful for otherapplications in addition to thermally based weather modification. Onesuch application is to aid in ocean uptake of atmospheric CO2. Oceansare natural CO2 sinks, and represent the largest active carbon sink onEarth. This role as a sink for CO2 is driven by two processes, thesolubility pump and the biological pump. The former is primarily afunction of differential CO2 solubility in seawater and the thermohalinecirculation, while the latter is the sum of a series of biologicalprocesses that transport carbon (in organic and inorganic forms) fromthe surface near-euphotic zone to the ocean's interior.

The solubility pump is a nonbiological effect wherein CO2 firstdissolves in the surface layer of the ocean. This surface layer canbecome saturated and its ability to absorb more carbon dioxide declines.Use of this system to promote mixing between surface and subsurfacewater enhances the efficacy of solubility pump in at least two manners;by net transport of CO2-enriched water downwards, as well as by reducingthe temperature of the surface water, thereby increasing its ability todissolve CO2. The solubility pump enhancement induced by this system canalso be useful for increasing ocean uptake of other atmospheric gases,such as methane, nitrogen oxides, sulfur dioxide, etc.

While the biological pump currently has a limited effect on CO2 uptakeintroduced into the atmosphere by human activities, there have beensuggestions to increase the carbon sequestration efficiency of theoceans by increasing the surface-layer phytoplankton concentration,which is in many instances limited by insufficient surface-layernutrients. Nitrates, silicates, and phosphates are, for instance,largely absent from surface waters, yet are considerably more abundantin subsurface oceans. These exemplary systems and methods can be used tomix surface and subsurface waters, thereby transporting nutrientstowards the surface. This increase in surface nutrients can be useful inincreasing the CO2 biological pump by increasing surface-layerphytoplankton concentrations. Increases in surface-layer nutrients canalso be useful for increasing populations of water-based fauna or flora,both in oceans and in other water bodies, such as lakes, reservoirs,rivers, etc.

The benefits of these systems and methods in increasing mixing betweensurface and subsurface water is not restricted to use in oceans, but canalso be beneficial in other bodies of water, such as lakes, reservoirs,rivers, etc.

While particular aspects of the present subject matter described hereinhave been shown and described, it will be apparent to those skilled inthe art that, based upon the teachings herein, changes and modificationsmay be made without departing from the subject matter described hereinand its broader aspects and, therefore, the appended claims are toencompass within their scope all such changes and modifications as arewithin the true spirit and scope of the subject matter described herein.Furthermore, it is to be understood that the invention is defined by theappended claims. It will be understood by those within the art that, ingeneral, terms used herein, and especially in the appended claims (e.g.,bodies of the appended claims) are generally intended as “open” terms(e.g., the term “including” should be interpreted as “including but notlimited to,” the term “having” should be interpreted as “having atleast,” the term “includes” should be interpreted as “includes but isnot limited to,” etc.). It will be further understood by those withinthe art that if a specific number of an introduced claim recitation isintended, such an intent will be explicitly recited in the claim, and inthe absence of such recitation no such intent is present. For example,as an aid to understanding, the following appended claims may containusage of the introductory phrases “at least one” and “one or more” tointroduce claim recitations. However, the use of such phrases should notbe construed to imply that the introduction of a claim recitation by theindefinite articles “a” or “an” limits any particular claim containingsuch introduced claim recitation to inventions containing only one suchrecitation, even when the same claim includes the introductory phrases“one or more” or “at least one” and indefinite articles such as “a” or“an” (e.g., “a” and/or “an” should typically be interpreted to mean “atleast one” or “one or more”); the same holds true for the use ofdefinite articles used to introduce claim recitations. In addition, evenif a specific number of an introduced claim recitation is explicitlyrecited, those skilled in the art will recognize that such recitationshould typically be interpreted to mean at least the recited number(e.g., the bare recitation of “two recitations,” without othermodifiers, typically means at least two recitations, or two or morerecitations). Furthermore, in those instances where a conventionanalogous to “at least one of A, B, and C, etc.” is used, in generalsuch a construction is intended in the sense one having skill in the artwould understand the convention (e.g., “a system having at least one ofA, B, and C” would include but not be limited to systems that have Aalone, B alone, C alone, A and B together, A and C together, B and Ctogether, and/or A, B, and C together, etc.). In those instances where aconvention analogous to “at least one of A, B, or C, etc.” is used, ingeneral such a construction is intended in the sense one having skill inthe art would understand the convention (e.g., “a system having at leastone of A, B, or C” would include but not be limited to systems that haveA alone, B alone, C alone, A and B together, A and C together, B and Ctogether, and/or A, B, and C together, etc.). It will be furtherunderstood by those within the art that virtually any disjunctive wordand/or phrase presenting two or more alternative terms, whether in thedescription, claims, or drawings, should be understood to contemplatethe possibilities of including one of the terms, either of the terms, orboth terms. For example, the phrase “A or B” will be understood toinclude the possibilities of “A” or “B” or “A and B.”
